Webface τof a cone σis a subset of the form u−1(0) ∩σfor u∈M. A cone complex Σ is a poset diagram of face inclusions in RPC such that all faces of cones in Σ are also in Σ. A morphism of cone complexes f: Σ →Γ is a collection of morphisms f i: σ i 1 →γ i 2, one for each cone σ i 1 of Σ, none of which factor through a proper ...

An element a ∈ (A, ≼) is called maximal if there is no other element b ∈ A such that a ≺ b. That is, an … Webcomplete poset if every countably directed subset D ⊆ L has a least upper bound supD in L. An upper set U of L is σ-Scott open if for every countably directed subset D ⊆ L, supD ∈ U implies D ∩ U 6= ∅. All σ-Scott open subsets of L form a topology, called the σ-Scott topology and denoted as σc(L). Let L be a poset. costituito da depositi glaciali
